* Fortgeschrittenere (aber ebenso einfache) Techniken zur Deklaration **tief verschachtelter JSON-Modelle** (dank Pydantic).
* **GraphQL**-Integration mit [Strawberry](https://strawberry.rocks) und anderen Bibliotheken.
* Viele zusätzliche Features (dank Starlette) wie:
    * **WebSockets**
    * extrem einfache Tests auf Basis von HTTPX und `pytest`

因此，（在浏览器中运行的）前端会尝试访问 `/openapi.json`，但无法获取 OpenAPI 模式。

因为我们的应用使用了路径前缀为 `/api/v1` 的代理，前端需要从 `/api/v1/openapi.json` 获取 OpenAPI 模式。

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip | 提示

* Técnicas más avanzadas (pero igualmente fáciles) para declarar **modelos JSON profundamente anidados** (gracias a Pydantic).
* Integración con **GraphQL** usando [Strawberry](https://strawberry.rocks) y otros paquetes.
* Muchas funcionalidades extra (gracias a Starlette) como:
    * **WebSockets**
    * pruebas extremadamente fáciles basadas en HTTPX y `pytest`
    * **CORS**

そのため、フロントエンド（ブラウザで動作）は `/openapi.json` にアクセスしようとして、OpenAPI スキーマを取得できません。

このアプリには `/api/v1` のパスプレフィックスを付与するプロキシがあるため、フロントエンドは `/api/v1/openapi.json` から取得する必要があります。

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```
